An elevated pulse rate in children can be associated with hyperactivity, as this state typically involves increased physical movement and metabolism. When children are hyperactive, their bodies require more oxygen and energy, which leads to an increase in heart rate as the cardiovascular system works to supply the muscles and organs with the necessary blood flow. This heightened state of activity naturally stimulates the heart, resulting in a faster pulse.

Other states mentioned, such as deep sleep and calmness, are generally associated with a lower pulse rate since the body is in a state of rest and requires less cardiovascular activity. Dehydration can also impact the pulse rate, but it may lead to a range of physiological changes, including potential increases in heart rate, though this is often in the context of compensatory mechanisms rather than a direct correlation like hyperactivity. Understanding these physiological responses helps to better comprehend how different states can affect heart rate in children.
